Video Enhancement.
Works on enhancement have tried to tackle correction of compression related spatial and temporal artifacts such as blocking, ringing, flickering, and color changes from reduced color depth with decreasing bitrate.
Deblocking has been tackled using design of targetted correction filters[1]}, [2]}, Kalman filters[3]}, and optical flow[4]}, [5]}.
Some works performed video enhancement in conjunction with super-resolution by incorporating frame alignment modules[6]}, offline detection of non-PQF's (Peak Quality Frames)[7]} and combination of learned upsampling filters with GANs[8]}.
